Re: [PATCH v2 2/4] libcc1: set debug compile: Display GCC driver filename

Hi,

already approved, reposting just to keep it a part of the series:
	https://gcc.gnu.org/ml/gcc-patches/2015-04/msg01301.html

As discussed in
	How to use compile & execute function in GDB
	https://sourceware.org/ml/gdb/2015-04/msg00026.html

GDB currently searches for /usr/bin/ARCH-OS-gcc and chooses one but it does not
display which one.  It cannot, GCC method set_arguments() does not yet know
whether 'set debug compile' is enabled or not.

Unfortunately this changes libcc1 API in an incompatible way.  There is
a possibility of a hack to keep the API the same - one could pass "-v" option
explicitly to set_arguments(), set_arguments() could compare the "-v" string
and print the GCC filename accordingly.  Then the 'verbose' parameter of
compile() would lose its meaning.  What do you think?

GDB counterpart:
